Han-Wen Nienhuys 28e7a6d3fe bazel: bower support
* npm_binary (download tarball packaged npm apps)

* bower_archive (download a zip file, to be put in WORKSPACE)

* bower_component (defining a bower library, with dependency )

* bower_component_bundle (zipping up libraries together)

* js_component (insert plain js file into bower component bundle)

* bower2bazel.py: run bower to find dependencies, generate a .bzl to
  define archives and define components

Tested:

 python tools/js/bower2bazel.py -w lib/js/bower_archives.bzl -b \
    lib/js/bower_components.bzl

 bazel build polygerrit-ui:components
 unzip -v bazel-bin/polygerrit-ui/components.zip > /tmp/baz

 buck build polygerrit-ui:polygerrit_components
 unzip -v buck-out/gen/polygerrit-ui/polygerrit_components/polygerrit_components.bower_components.zip > /tmp/buck

 diff /tmp/buck /tmp/baz

The diff corresponds to newer file versions pinned through bower2bazel.
